Application filed November 5, 1914. Serial No. 870,335.

T all rLai/wm it may concern:

Be it knownl that we, GEORGE W. GwrNN and ANDREW GwYNN, citizens of theUnited States, residing at lSalt Lake City, in the county of Salt Lake'land State of Utah, have invented Acertain new and useful Improve- -mentsin Railway-Switches, of which the following is aspecification.

Our lnvent'ion relates to improvements 1n railway switches, and refersto thanA class of switches which are opened by means carried by the car.

The object of our invention is the provision of means which will beabsolutely reliable in operation, which wil'l be Simple, strong anddurable to withstand hard usage, and whichwill be inexpensive ,ofproduction, to insure an efficient and practical 1mprovement of thischaracter.

IVith this object in view our invention consists of a railway switchembodylng novel features and combination of parts substantially asshown, described and particularly defined bythe claims.

Figure 1 is a plan view of the main track,

switch or point and switch mechanism,-Fig.

' 2 is a perspective view of the means for operating the switch-mechanism and carried by the'car, Figs. 3 and 4 are detail views oi'parts of the switch mechanism.

In the drawings -The numeralyl designates the main track; 2 the siding;and 3 the pivoted point which is confined in its movement by the stripor rail 4. In, the surface between the rails is sunk the casing or 'box5 and the larger casing or box 6,' which are connected by the pipe 7,and coupling sleeves 8. In the casing 5 is formed a bracket 9, to whichis pivoted at 10, the right vangled shaped lever 11, one arm 10 of whichhas secured thereto the bracket plate y12, and in openings 13, of thearm and plate r is mounted the pin 14, which projects up through thecurved slot 15, in the cover platelG. The pin is provided with a collar14, against which and the arm lQ, exerts the tension of' a coiled springthis normally forcing the pin upward to project its upper 'end above theslot in the cover plate 16.

To the other arm 10X, of the lever 11, is secured one end 17, of the rod18 whose other end 19, is secured to the arm 20, of the angle lever 21,fulcrumed at 22, in theA bracket 23, and having its other arm 24` formednear its end with an opening 25, to receive the threaded rod 26. Uponthis threaded rod is placed the pair ci nuts 27, which serve to adjustthe tension of the pair 'of coiled s Jrings28, which surround the rod26, and be r at their outer ends against the nuts 27 and at their innerends .against the opposite faces of the arm 24. The arm thus has aspring orcushion connection with "the threaded rod which prevents injuryto the arm or rod and alsopermits the tension of the springs to beadjusted to suit the circumstances. The inner end of said threaded rodis mounted at 29., in the turn buckle 3 0, whose other threaded sleeve29 receives the threaded end 31 of the pin 32,- which is4 connected atits headed end' 33, to the pivoted switch point. It will thus be seenvthat the two cases or boxes are arranged be'tween the rails, sunk in theground and protected from the' elements by covers and that the pin 14,l

will always be retained above the cover of thecase by the spring.

To operate the switch' from the car we` provide a novel mechanism whichwe will now describe.

The platform 34, ofthe car is provided with an opening 35, around whichis lsecured the guide plates 36, the lower of which is formed with asleeve 37, and guided in the opening and plates is the plunger 38, hav!ing at its upper end a treadle or foot pin 38 and having its lowerendsecured to the yoke shaped frame 39. To the frame 39 and the sleeve37, are secured the pairs of plates 40, each having a'hook 40', and tothe hooks of the series of plates are connected the loops 41 on the pairof coiled springs 41.

It will thus be seen that the plu-nger isforced down by pressure of thefoot and upon releaseof the foot the springs instantly raise the plungerwith theA yoke shaped frame 39 connected to the' plunger.

To the frame at its lower ends 39 is secured the shoe for operating 'theswitch mechanism and th'isshoe is ofpeculiar and novel construction andconsists of the pair of oppositely fiared arms 42, and the pair ofoppositely fia-red guides or boxes 43, the

ber 42 withv theq pin 14 will partly throw the' 'Switchpoint andthealined member 43 coni tinues l the momentum of the switch point and the4and 43.
